What it is about
Adobe Acrobat ist ein Programm für die Erstellung und Betrachtung von Dokumenten im Portable Document Format (PDF). Adobe Reader ist ein Programm für die Anzeige von Dokumenten im Portable Document Format (PDF). Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Adobe Acrobat und Adobe Acrobat Reader ausnutzen, um beliebigen Code auszuführen, vertrauliche Informationen offenzulegen oder einen Denial-of-Service zu verursachen.
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- beliebigen Code auszuführen
- vertrauliche Informationen offenzulegen oder einen Denial-of-Service zu verursachen

- Adobe Acrobat Reader 26.001.21662

Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
